I agree with Garlic_Sauce statements, and here is my take on this.
I consider myself a power webnovel reader as I keep on average 20 novels in the library and read over 20 chapters daily depending on the novel, update frequency and my level of interest. If its high, I am likely to go much more once available. Now, I have reached a point whereby I am more or less forced to pay premium which I hate because i will not be able to enjoy the books that I like a lot. Now I do understand trying to make a living, having expenses etc. but I feel this is BEYOND HIGHWAY ROBBERY especially for those power readers. This is very applicable to novels with over 100 chapters and you are charging 3-11 SS per chapter - that's not fair. This is also related to novels that have on average over 1m readers daily. It's like Qidan gives you a lollipop to taste and once you lick it they yank it out of your mouth hard, hence you lose your teeth & then some. That's just nasty on a whole, when Qidan do this they are likely lose their key customers and turn off potential new customers. I try to do the calculation for a SS 2500+(750 bonus chapters) - USD 50, as the 50 SS won't cut it. In my country, should I proceed with this I would be paying an minimum cost of JAM$7,000 and this is not a monthly fee, nor its cheap because that can take care of some key expenses. Let's say I am a fan of one of the novels with over 1,000 chapters paying an minimum cost of 4 SS per chapter it goes very fast (4000 SS) and its just one novel which is not yet complete. What about other similar stories, this gets expensive very fast, before you even complete 10 chapters. What you are more or less doing is encouraging the power reader to spend is over $100 US for incomplete BOOK/S. This is not feasible for the customer wherever they are and I Repeat pretty costly.
Should Qidan insists on charging a fee for reading books then I think Qidan needs to provide an SS monthly, quarterly, semi-annual and annual flat rate which would be applied for all novels. Once that is paid, the power user should have access to those novel, chapters etc. regardless, as that fee is already covered. That way there is a balance and the price must be reasonable, I doubt if Qidan will lose at all if they do this. Do not turn off the customer, nor make them poorer than they already are.
Also, I am aware that at times you can lose your SS from lack of use. What happens then, lets say I decided to give myself a break from coming here for awhile eg. 1 - 2 months, reason I have to prep for exams. What happens especially when its valid for 90 days only? A part from the benefit of reading a chapter, what else can the SS cover for the reader?
Qidan needs to look at the big picture medium - long term especially if they wish to retain their power readers and obtain new customers. Come up with a solution that is more customer friendly than rip off friendly.
Long post that needed to be said. Have a good weekend.
